When the brake is applied during position control, the motor cannot rotate even if there exists position
error. For this reason, the integral term accumulates which sometimes causes an overload trip to oc-
cur
. When ASR integral term cancel “P-SEL” allocated to a multifunction input terminal is turned ON,
the integral term of the speed controller is canceled and P operation is performed.
